Memory card with push-push connector

Abstract

The present invention, roughly described, pertains to a small memory card that includes features which allow the memory card to be more easily handled by a user. In various embodiments, the memory card can include a chamfer and/or a raised portion that allows the memory card to be more easily grabbed by a human hand (or mechanical device) and also provides additional room to store passive devices such as capacitors and/or resistors. Because different electronic devices use different types of memory cards, an adaptor is provided that allows the memory cards disclosed herein to be used in ports or connectors on electronic devices that are meant for other types of memory cards.
